While signing up, you are given the option to let the commissioner edit your picks or to get email alerts before the first game. These are optional, but I'd recommend both for the reasons [below]

However, like last season, in the case of extenuating circumstances, the commissioner (me) is allowed to edit your picks, if you choose to enable the option. This will be on a case by case basis. If you were busy Sunday morning and didn't get back until 12:58, post your picks in this thread and I'll edit your bracket. If you slept until 2:15 after a night of partying, don't expect me to give you the same privilege.
